Small Python script that returns a string encoding (linux) laptop battery status. Each char represents 10%. a `-` means empty, `🞂` means charging, and `🞀` means running on battery power. Strongly inspired by Steve Losh's zsh prompt http://stevelosh.com/blog/2010/02/my-extravagant-zsh-prompt/#my-right-prompt-battery-capacity, but changed quite a …
